The data used were based on topographic and Bathymetric data of Porong River, cross-sections of the river, and terrain sediment distribution patterns. The study conducted field and secondary data analysis, hydrological analysis, oceanographic analysis of Mura River and river hydraulic analysis. The study concludes that to maintain its capacity and prevent negative impacts, it is necessary to protect the cliffs and embankments along the segment of the river. To protect the community pond area, overburden and/or river dredging activities along with the segments from the branch to the estuary of the river are needed. Furthermore, it is also necessary to add artificial inputs such as submersible Kribs that are arranged on piles to deal with problems of river sediments in the mouth of Porong River","PeriodicalId":432135,"journal":{"name":"Civil and Environmental Science","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126785451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are suffering from severe watershed erosion and a heavy load of volcanic ash ejected from the eruption of Mount Kelud. Wlingi reservoir is significantly affected by recurrent volcanic activities of Mount Kelud. After the 2014 eruption, the capacity of Wlingi reservoirs decreased by 82.5% or only 3.70 million m3 from the initial capacity of 24 million m3. To analyze the impact of volcanic eruption disaster on reservoir sedimentation an integrated numerical model of sediment is required. The Fujiyama model is an integrated sediment runoff model using a basin model composed of unit channels and unit slopes. The model seems suitable for a mountainous basin. The simulation results from the model explain that the mechanism of transporting sediment into the Wlingi Reservoir can be explained based on the type of sediment transport. The movement of sediment originating from Kelud Mountain in Kali Lekso is strongly influenced by rainfall duration compared to the intensity of the rainfall. Also, the simulation model results explained that the mechanism of sediment transportation is dominated by suspended load or bed load which when large discharges will move with the mechanism of suspended load sediment transport.","PeriodicalId":432135,"journal":{"name":"Civil and Environmental Science","volume":" 20","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120832721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated hydraulic performance of CBP as an impact of surface roughness condition, under high rainfall intensities, saturated sub-base layer, and various slope surfaces. We conducted experiment using a 2 m by 6 m of rectangular CBP layer with herringbone 90 and basket-weave pattern. We used a modified dye tracing method in view to monitor the surface flow velocity under various high rainfall intensities. The results showed that hydraulic performance of surface runoff in the CBP layer was more influenced by the surface roughness condition. The roughness condition was very sensitive to the change in surface configuration of the CBP. The relationship between rainfall intensity, surface slope and roughness number followed polynomial functions. A further study is required to investigate the appropriate quality of CBPs, which have high durability applied over a steep slope surface and under high rainfall intensities.","PeriodicalId":432135,"journal":{"name":"Civil and Environmental Science","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125885095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
